Hi!

I was wondering if there were any intructions how to connect the HL7812 via UART? Maybe using an STMOD+ module like in the picture below?

I saw that there were enable and disable jumpers? I think this is how to boot the HL7812.
My question is if anyone has experience integrating a STM32 with the HL7812 with UART?

Thanks!
